They find the oldest rock
01/11/2008 | Elhuyar
The oldest rock found so far has 4,030 billion years and is located in the northwest of Canada. And precisely in Canada, in Hudson Bay, geologists at McGill University in Montreal have discovered an even older rock. It is estimated at 4,280 million years. For the calculation of age have been based on two rare elements, neodymium and samarium, which disappear at a certain rate over time. With the rock, researchers will be able to analyze the evolution of the Earth. In addition, they will look for life tracks.
